Relative to hop powder pellets:
-	most of the alpha acids are converted to the equivalent magnesium iso-alpha form.
-	presence of magnesium and magnesium oxide
-	slight reduction in beta acids content

Advantages
Relative to hop powder pellets:
-	reduced requirement for cold storage
-	increased utilization of alpha acids (55 - 60%)
